Generic Attribute Registration Protocol (GARP) VLAN Registration Protocol (GVRP)
eneric Attribute Registration Protocol (GARP) and VLAN registration over GARP is
called GVRP. GVRP is defined in the IEEE 802.1q and GARP in the IEEE 802.1p
standards. In order to utilize the capabilities of GVRP, GarrettCom Inc. strongly
recommends that the user is familiar with the concepts and capabilities of IEEE

VRP concepts
VRP makes it easy to propagate VLAN information across multiple switches.
ithout GVRP, a network administrator has to go to each individual switch and
enable the necessary VLAN information or block specific VLAN’s so that the
network integrity is maintained. With GVRP this process can be automated.
j
It is critical that all switches share a common VLAN. This VLAN typically is the default
VLAN (VID=1) on most switches and other devices. GVRP uses “GVRP Bridge
Protocol Data Units” (“GVRP BPDUs”) to “advertise” static VLANs. We refer to GVRP
BPDU as an “advertisement”.
GVRP enables the Magnum 6K family of switches to dynamically create 802.1q-compliant
VLANs on links with other devices running GVRP. This enables the switch to
automatically create VLAN links between GVRP-aware devices. A GVRP link can include
intermediate devices that are not GVRP-aware. This operation reduces the chances for
errors in VLAN configuration by automatically providing VLAN ID (VID) consistency
across the network. GVRP can thus be used to propagate VLANs to other GVRP-aware
devices instead of manually having to set up VLANs across the network. After the switch
creates a dynamic VLAN, GVRP can also be used to dynamically enable port membership

There must be one common VLAN (that is, one common VID) connecting
all of the GVRP-aware devices in the network to carry GVRP packets.

GarrettCom Inc. recommends the default VLAN (DEFAULT_VLAN; VID

port of the Magnum 6K family of switches. That is, on ports used as GVRP links, leave
